[john61ct]

Anyone tried /has opinions on this new cyclone kit?
More reliable?

link?

If you put more than trifling pedal power through that, it will skip. Less than 120 degrees of sprocket engagement is a recipe for intractable problems.

[jordison]

I suspect the chain wheel just works as chain guide.

maybe when just pedaling it will skip.

With the motor closer to the bb perhaps it won't twist as much under load.

From pictures it seems the new kit doesn't have second bracket connecting rear of the motor to BB.
So IMHO they made it worse.

PS. That poor sprocket engagement will only become issue on the "walk of shame" scenario

[jordison]

they r not that crazy

there is a clamp on the left side

i think its amazing that after al these years they still use these clamps

Some short clips for inspiration…


Snow riding. If you get the chance try it out.

Just short clips I texted to friends.

The cyclone thread is from 2015. Wow how time flies. I see it becoming less popular now, hard to get and keep running all that stuff and there’s better choices like cyc and lightning rods for those who’ve learned to figure it out with the cyclone. But I really like the fatbike ride and tire and was wondering about something like the sur-ron in the snow. I’m not impressed after watching this video below. I really want to get 45nrth wrathchild tires down the road, $250 each ouch. We’ll see. Exploring in the snow is really fun even if it’s the woods down the street from my house.

I use my Cyclone almost daily for trail riding; including snow and cold temps (currently -29C today). The motor itself is a brute and takes everything I throw at it. I ride with 26 x 4.8 Maxxis Minions and although they aren't really a "snow" tire like many of the 45nrth etc...; they perform great in the snow. The key is to lower your pressure for max float without the rim bottoming out or having too much self steer from the tire.

My max snow depth on that bike is about 20cm and then it's no longer ridable. Many expensive fat bike tires like the wrathchilds you mentioned are also designed to be lightweight; I'd rather have the durability of the Minions + a good tube than less weight. I was also able to stud my front Minion with some Aliexpress studs (see my Blizzard build).

Has anyone tried the "tiny" 200 phase amp controller in a high power application yet? Looks too good to be true.

Just bringing this up in the ranks. Not so easy to get anymore but a lot of us got our start with the cyclone. 60a version here. It’s worth it to start out.

Hi Everyone, It is always a pleasure to read your experiences. I was thinking of filling my motor/gearbox with Automatic transmission oil. ( 30% of the volume left empty) so that could benefit to the cooling and to the noise of the gears. What do you guys think

[DingusMcGee]

Overheating? Likely the heat comes from the where the wiring is in the motor and not the planetary gear box. ATF? Try it. Maybe the seals will hold it? Get a bigger motor if this one gets hot. Add some thermocouples to some locations on the motor and test.

The noise location?? Maybe before you condemn the gearbox & grease invest in sound intensity meter? Then you can measure sound intensity (generation) at the gearbox and at the dual sprocket bottom bracket hub.

I just had an unmounted Cyclone 3k motor with gearbox housing in place & OEM grease running on the bench -- very quiet.

I have a sound intensity meter and have used it on several bikes with Cyclone 3k motors. The preponderance of noise comes from the location where the 2 chain drives meet on the BB axle.

Lol what the hell is that... budget cuts? Why didn't they go with cardboard. I can only imagine the flex

I'm fortunate enough to have a prototype of a heavy duty bracket made by sickbikeparts, don't mind the zip tie to downtube connection... it gave up pretty quickly lol, replaced it with u-bolt, its rock solid now.
Sadly after looking at their site it seems they gave up on the cyclone3k and most likely this bracket.

Without pedaling, I've seen a maximum speed of 35mph/56kph. My battery pack is a 14s10p pack which is 58.8 volts fully charged and between 52.5 -55 nominal. The controller is listed as a 40amp continuous and 100 amp peak capable. I use a PowerLog 6s meter to measure only 6 cells of my pack and I have seen 50amps peak current draw. I suspect that's the most i'll ever get out of my 18650 cells.
if you had a battery pack capable of 60amps or more, I'd guess the motor (and correct gearing) would push you over 45mph/72kph. My bike is on the ragged edge at 35mph and I usually ride below 30mph.

What range are you getting with that setup? How agressive? Im trying to get an idea of what battery capacity I would want.
